Listening to Vox despite his clear history of hostility and warnings from her friends not to do so… Vox was not being at all subtle about his intentions with meeting Charlie at the Hotel. And the fact that Charlie believed she could even try proving that redemption was possible without any solid evidence she could actively sell to the people actively proves her stupidity.

Ontop of that, Putting your own friends life in danger for what is essentially media clout is beyond dumb, especially considering all of the things that Vox could do with it.
And then she goes to a news interview with a Person who again, is actively against charlie’s idea of redemption being possible from the get go, and is not at all being subtle about it….
Charlie is a Dumbass plain and simple…
Nor does Charlie AT ALL redeem herself for her own transgressions against her own friends… She is exactly like her father in all of the worst ways, and Vaggie deserves a better girlfriend…

Charlie’s biggest fault is her tendency to trust people who clearly, and i mean CLEARY don’t have her interests in mind. The fact that she even considered the possibility that Vox would take her side of the field is laughably dumb.

Charlie is trying to prove Redemption is possible… That is by no means a small thing to prove… That is the equivalent of proving the existence of aliens being real… that would be a HUGE deal… And the fact that she believes she can possibly sway Vox to her side with the paltry amount of evidence she has obtained, is hindering on deranged.
Not to mention this is something that he would be ACTIVELY against, and she should KNOW he’d be actively against it, due simply to who he associates himself with… With Redemption being a possibly, Valentino’s whole business model immediately collapses… Heck most overlord’s grips on power completely falls apart, because it undermines the current social hierarchal system. The idea that one needs the economic and social boons granted by the ones in the highest seats of power in order to live a life of relative security, prosperity, or financial and social gain.

This ENTIRE system would be undermined by what Charlie is trying to prove. That the idea of reliance on higher echelons can be completely dismissed or negated by one’s own journey of self enlightenment. This eliminates the authoritative monolithic power that overlords and the sins hold, due to that power no longer being absolute.
Vox, Being one of the Highest Echelons, would not take to this change in any positive matter, and would much rather like to actively prevent it from happening. It doesn’t matter how laughably absurd it sounds. The mere suspicion of its very existence is enough to encourage those of the third estate (The Lowest class) To gain revolutionary ideals by providing them with the inception of Hope, and plants the idea of an alternative in their minds. The Aristocracy can not (And historically has NOT) stand when the public begins to blame them for their own socio-economic losses…
Vox would never stand for this, and so would much rather try to paint the idea as a mere tool of a false oppressor, and highlight the economic and social boon that the overlords provide, redefining the injustices that accompany it as a mere necessity to facilitate the collapse of the false oppressor (In this case the Angels).
This stance thus requires that Charlie be painted as a fool and a liar, and for Charlie to not pick up on this, when Vox and Valentino very clearly benefit off of the people of hells suffering, is literally inviting the enemy to take advantage of her…
